I have done hundreds of Hrs and never seen WM drop a WOT air fuel 1.6 points , if this did happen then you had far to much WM going in and effecting your air fuel gauge and performance
I will NEVER tune the engine / fueling to run water meth , In my opinion this is the most dangerous thing you can do , if the
Tank runs out of meth
line comes loose
jet stops up
turn on switch doesnt work
You will loose an engine faster then you can let off , tuning for WM in my opinion is foolish , use it for safety and it works ok
